AUTOMATIC GATE."A

Application led'fFebruary 7, 1920..(Seri1 No. 356,811; Y

provide a gate adaptedfto swingin averti l cal plane, and one which willbe normally` held in a vertical or closed position.

A turther object of the invention is to provide a gata-adapted to beoperated by the force for a vehicle, moving into engagement therewith,thereby .moving the gate from a vertical or closed position, to a hori-lzontal, or open position, to permit' the vehicle to pass thereover.`

A further object of the invention is to provide a device of thischaracter, which will automatically move to its closed posiy tion, aftera vehicle has passed thereover.

A further object of the invention is to provide a gate, having means forpreventing the gate from movingto its closed position, until the vehiclepassingthrough the' gate, has entirely cleared the gate.

lilith the above and other objects in view,- which will appear as thedescription pro ceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that vari ous changes in theprecise embodiment of the invention shown can be made without departing`from the spirit of the invention.

Referring to thc drawings:

Figure 1 illustrates a view in elevation, of a gate constructed inaccordance with the present invention. Fig. 2 illustrates a sideelevational view, partly in section, showingthegate in a semiopenposition, and

3 illustrates a detail view of the hinge employed in connection with thegate.

Having reference to the drawings in detail, the reference characters 5and 6 designateithe side posts of the gate, which are preferably hollowthroughout their lengths, the lower ends thereof being embedded in aconcrete foundation 7, but it is to be understood.y that any suitable'form of foundation, which will securely anchor the posts 5 and 6 intheir'vertical positions'gmaylbe employe'd. f Y Disposed betweeny theposts' 5 and, and

. constructedto operate in ai vertical plane, is

the gate proper J8, whichf includes the top and -bottommbars ^9 andfllOrespectively, which bars are connectedlby the'end bars 11 vand .12,allotA the bars, being connected -by a suitable, substantially'heavygwwire imesh 1 3, but itis of course apparent that the meshSpecification of Letterslatent. Pajjn'ted 0013626, 1v19205".

einployedrxin the` gate construction, should conformto .the type of meshused 'in the construction ot' the' fence associated there- The gateyconstruction also includes the central bar` '14, whichfhas its ends'connected A to thebars Qand 10, -by means ofthe lcouplingscl, thehorizontally 'disposed buffer bar 16, havingconnectionwith the centralVvbar 1&1-, intermediateits lengthythe ends thereof `havingconnectionywith `the end bars and 12, "as atk 17. 'i This-buffer bari 16, isdisposed vin suitable spaced' relation with the bottombar 10, sothatffthe vsame willA be engaged by they periphery of the' front wheelsof aV vehicle, passingtthrough the gate, ythe buffer-bai"beingforthepurpose of receivingthe strain', or shockdirectedto thev gate, duringthe opening operation.

Hinge members 18, which are inthe form of cleats, are constructed toembrace the lower bar 10 of the gate, the same being disposed insuitable spaced relation throughout the length of the lower. bar l0,whereby the gate is uniformly supported to permit the same to movefreely, during the opening and closing operations.

As shown, these cleats, are preferably scmi-circular in formation, toconform to the contour of the lower bar 10, so that the gate will befree oiA lateral movement within the hinge elements 18. Supportedundereach oi' the hinge elements 18, is a relatively flat member 19,which is provided with openings, in its respective ends, which openingsregister with the openings 20, formed in the right angled ends 21,forming a part of the respective cleats.' Bolts 22 pass through thestantially intermediate the lengths of the bars il and l2, and providemeans for securing the free ends of the iiexible members 24:, to thegate, the opposite ends of said iiexible members 2d, having connectionwith the weights 25 and 26 respectively, the intermediate portions oithe flexible members 2li passing over the pulleys 25, supported tooperate in a vertical plane, adjacent the up per ends oi"- the posts 5and 6, the pulleys 27, being arranged in pairs, to operate in a verticalplane, and provideiguides for the flexible members 2A, to prevent theflexible members from being displaced from the pulleys 25, when lateralstrain is brought to bear on the flexible members 24, `during theopening and closing operations.

Ii? it becomes necessary to hold the gate, in its open position, it isonly necessary to move the connection between the gate and flexiblemembers, to the bracket members 20, which, due to their locations withrespect to the pivot point or' the gate, tend to prevent closing oi'theq gate. rlhe extension 26, forms acontinuation of the central bar 14,and is provided tor the `purpose of contacting with the body of thevehicle passing thereover, for holding the gate in an open position, andpreventing the same from closing, bei'ore the vehicle, has cleared thegate.

From an observation oflTig. 2, it will be apparent that in operation avehicle to pass through a gate constructed in accordance with thepresent invention, moves into engagement with the butler bar 16,whereupon turther movement of the vehicle causes the gate proper to moveto a horizontal position, which position permits the vehicle to y tion.

Having thus described the' invention what is claimed is:

l. A vertically swinging gate including a top and bottom bar, meanshaving connection with the bottom bar forming hinges, a butter barsupported in spaced relation with the lower bar, hollow posts associatedwith the gate, means operating within the hollow posts and havingconnection with the gate, for holding the gates, normally, in a verticalposition, and means carried by the gate for restrictingr the swingingmovement-thereof.

2, A vertically swinging gate including top and bottom bars, means iiorpivotally connecting the gate to a support, a buffer bar extendingtransversely of the gate and in close proximity with the bottom barthereof, hollow posts for supporting the gate, means for moving the gatein one direction, a central bar forming a part of the gate, one end ofsaid central bar extending beyond the ujper bar, said bar adapted tocontact with a vehicle rpassing over the gate, for restricting movementoit' the gate-l in testimony that I claim the foregoing as my own, Ihave hereto affixed my signature in the presence of two witnesses.
